IMPROVBMENT IN ROTARY-HYDRO-PNEUMATIC PUMP&

The Schedue referred to in these Iotter Faton: nd making part of thaume.

To-all whom it may dono-em.-

Be it known that'I, HENRY M. PAINE, of the city of Newark, State of NewJersey, have invented a new and useful Rotary Air-Puup; and I do herebydeclare that the following is a full, clear, and exact description ofthe construction and operation of the same, reference being had to theannexed drawings making part of this specifieation.

The object of my invention is two-fola; first, to secure a steady blast,and second, the surclarging of the air with fluid particles.

In order to accouplish these results I clivicle a cylender, A, Figura 1,into copartmeuts, JJ JJ. -The division walls B B B B, figs. 1 and 2,which is a longitudinal cross-section, extend about fourfitths of the.cylinder's length, and the end of the cylinder is cep ped with a head,C, fig. 2, and thus forms a-chamber, D.

Each copartment ou the opposite end of the eylin- 'der communicates withthe outer air by means of helical caps, E, figs( 2 and 3. Thechamber-euds, J, figs. 1 and 2, are separately closed, and thecopartments communicate with the chanber D through the valves H, figs.1, 2, and 3.

The division walls B, figs. 1, 2,.aud 3, do not meet the shaft F, butleave a free space, Gr, fig. 2, communieating with all the copartments.

Iu order to fully saturate the air I place wire-gauze or other porousdaphragms L, figs. 2 and 3, in the copart-ments.

If the cylinder be immersed below the wall-opening G, and rotated, airwill enter at the openings I, figs.

2 'and 3, and, travel-sing through' the diaphragms L, pass into thechamber D through the valves H, fig. 2, and car'ied from thence to theplace of its use by means of a siphou pipe, not shown, entering at N,fig. 2. The air in travel-sing the porous diaphragus will becomesatura-ted with partcles of whatever fluid the cylinder may be immersedin.

As the cylinder rotates a pressure willhe generated in the chambers D,which will keep the valves H closed till the pressurein the copartmentsequals that in the chamber before they open, and thus secure a continousblast.

What I 'claim as my invention, and desire to secure by Letters Pat-cnt,is

I. The diaphragms L L in the segmente-i ehambers, as arranged inrelation to the induction-openng and eduction-valves of a rotary1ydro-pueumatic pump, substantiallyas described. V i

2. A revolviug air-pump divided into segmental chambers containingdiaphragms, one or more, as shown, the several ehaubers cohmuuicating atthe axis of the cylinder, and the current of air entering' throughoblique openings in the cap forming one head of the cylinder, and beingforced through valves in a position near the opposit end, as thedivisions successively descend below the line of water in which thecylinder is immersed, all snbstantially as described.
